Manufacturers : Safety and surveillance electronics : Motion sensors
Motion sensors are used in a wide variety of applications and many different types of motion sensors havebeen developed. Motion sensors are primarily based on ultrasound, passive infrared (PIR) and radar detectors. An infrared detector of the motion sensor assembly outputs a signal responsive to infrared energy radiated from a source present in a field of view of the motion sensor assembly. PIR sensors are perhaps the most frequently used home security sensor. Ultrasonic motion sensors are commonly used for automatic door openers and security alarms. FM-CW radar sensors emit a swept frequency microwave signal and compare the frequency of the echo with its current emission frequency, producing a beat frequency proportional to range. Motion sensors are presently employed in a wide variety of applications. Motion sensors and accelerometers are widely used in VCR cameras and aerospace and automotive safety control systems and navigational systems, such as crash sensing systems. Motion sensors are commonly used in the field of mechanical engineering, particularly in the automotive vehicle industry, for applications of controlled brakes, position sensors, angular position sensors, motor-driven adjustment devices or for sensing wheel revolutions, active suspension systems, supplemental inflatable restraint systems such as air bags, and seat belt lock-up systems. Motion sensors are also used with bicycles to sense rotation of the wheel or pedal crank so that bicycle speed and cadence may be computed by a bicycle computer and displayed to the rider.
